FindMyShadow vs Pipe Sizer

Plot the shadows cast for your own custom scene, simply drawn right in the app! Generate reports and scene snapshots to print and share. Sun position plotter and shadow calculator that finds the position of the sun and its shadows at any location on the earth and on any date in the past or future. Uses include: - find out where the shadows are cast in your garden throughout the seasons to identify the perfect spot for your vegetable patch or decking - use the app to identify if your building extension will obstruct neighbours' light (or if your neighbours' extension will block your light!) - photographers can identify the perfect time to catch the light at the desired angle, or when and where to capture those sunrise and sunset shots - check if the angle of your roofline is suitable for solar panels

PipeSizer helps you quickly choose the right pipe diameter for water systems — for both pressure and gravity flow. PRESSURE PIPE SIZING • Size pipes from a target flow rate. • Set your maximum friction rate and velocity limits. • Calculations based on the Hazen-Williams equation. GRAVITY PIPE SIZING • Size pipes from a target flow rate. • Evaluate flow capacity and velocity under gravity conditions. • Calculations based on the Manning equation. KEY FEATURES • Automatic recommended pipe size based on your limits. • Multiple pipe materials with built-in coefficients (more added over time). • Works in both SI and Imperial (I-P) units. • Designed for engineers, plumbers, and irrigation/drainage design workflows. Feedback is welcome — it directly shapes upcoming updates.
